Ok so AF started 3/22 it's 4/4 and I'm still bleeding wth I have always had this issue but when I was younger my periods have been slightly regular prior months it's been very light this month it came down like a Ocean and still going ...Called my OB but there close till Monday I'm going thru pads fast and have been very fatigue I'm hoping it's nothing that will affect me having a another child DH and I have children from prior relationships but none together been ttc for 13months this is just frustrating
